Optical apparatus

ABSTRACT

An optical apparatus includes plural optical lens groups with a specified field of view, an optical sensor and a casing. After a light beam passes through any of the plural optical lens groups, a travelling direction of the light beam is changed. Moreover, after the light beam passes through at least one of the plural optical lens groups, the light beam is sensed by the optical sensor and converted into an image signal by the optical sensor. The plural optical lens groups and the optical sensor are accommodated and fixed within the casing. With different fields of view, the images, which are with different field angles, will be taken simultaneously and effectively an optical zooming effect is performed. In short, the optical apparatus has a single optical lens module, and is able to implement different optical functions simultaneously. Consequently, the overall volume of the optical apparatus is minimized, and the fabricating cost of the optical apparatus is reduced. Moreover, the assembling process is simplified, and the number of components to be assembled is reduced.

FIELD OF THE INVENTION

The present invention relates to an optical apparatus, and moreparticularly to an optical image capturing apparatus with extensionfunctions of wider fields of view (FOV) and/or simultaneous imagestaking with many FOVs.

BACKGROUND OF THE INVENTION

FIG. 1 schematically illustrates the structure of a conventional imagecapturing unit. As shown in FIG. 1, the image capturing unit 1 comprisesan optical lens group 11, an image sensor 12 and a casing 13. Theoptical lens group 11 comprises at least one lens for allowing anambient light beam to pass through. After the light beam passing throughthe optical lens group 11 is sensed by the image sensor 12, the lightbeam is converted into an image signal by the image sensor 12. Accordingto the image signal, a corresponding image is shown on a display device.The optical lens group 11 and the image sensor 12 are accommodatedwithin the casing 13 and securely positioned in the casing 13.Consequently, the optical lens group 11 and the image sensor 12 can benormally operated. In FIG. 1, the individual image capturing unit 1 isshown. However, since the current optical technology is increasinglydeveloped, the image capturing unit 1 can be minimized and installed ina portable electronic communication product. It is nevertheless thatthis traditional image capturing unit is with a specified field of view,unless a zoom lens group is utilized.

Moreover, the image capturing unit 1 of FIG. 1 is able to capture asingle image in each capturing process. For solving this drawbacks,plural image capturing units 1 are combined together in order to captureplural images at the same time.

FIG. 2 schematically illustrates the structure of a conventionalarray-type image capturing apparatus. As shown in FIG. 2, the array-typeimage capturing apparatus 2 comprises a frame 21 and plural imagecapturing units 1. The plural image capturing units 1 are in an arrayarrangement and in a rectangular distribution through the frame 21.Moreover, the image signals corresponding to the images acquired by theplural image capturing units 1 are transmitted to a back-end processor(not shown). After the image signals are integrated and processed by theback-end processor, the integrated image is shown on a display device.

Generally, the array-type image capturing apparatus 2 is able to captureplural images in each capturing process. However, the optical functionsprovided by the plural image capturing units 1 are identical. Forexample, the optical axes of the plural image capturing units 1 arealong the same direction. That is, there is no inclined angle betweenany two optical axes. Alternatively, all image capturing units 1 havethe same field of view (FOV). Because of fabrication the array lensgroups are with the same effective focal length (efl) generally.

Due to the limitations of the fabricating process of the currentarray-type image capturing apparatus 2, the imaging quality of the imagecapturing unit 1 is usually insufficient. For example, the imagecapturing unit 1 usually has a resolution of 1M˜2M pixels. Under thiscircumstance, the function provided by the array-type image capturingapparatus 2 is limited. Moreover, since the array arrangement of thearray-type image capturing apparatus 2 is complicated and plural imagecapturing units 1 are contained in the array-type image capturingapparatus 2, the applications thereof are restricted because of the highcost.

FIG. 3 schematically illustrates the structure of another conventionalimage capturing apparatus. As shown in FIG. 3, the image capturingapparatus 9 comprises plural lens modules 91 and a casing 92. The lensmodules 91 are fixed by the casing 92. Each lens module 91 comprises anoptical lens group 911 and an optical sensor (not shown). Moreover, theimage signals corresponding to the images acquired by the plural lensmodules 91 are transmitted to a processor (not shown). The processor maybe built in the casing 92. After the image signals are integrated andprocessed by the processor, a three-dimensional image is produced orshown on a display device. Likewise, the image capturing apparatus 9 isable to capture plural images in each capturing process. However, sinceplural optical sensors are installed within the casing 92, the volumereduction of the image capturing apparatus 9 is not obvious.

Therefore, while both of the overall volume and the fabricating cost aretaken into consideration, it is an important issue to allow the imagecapturing apparatus to capture plural images in each capturing processand allow the image capturing apparatus to flexibly provide differentoptical functions to achieve required optical efficacy according to thepractical requirements. Particularly if different FOV is demanded, thenit is necessary to embed different views (lens groups) with differentFOV for different lens groups. The advantages of the inclusion of moreFOV are nontrivial. Effectively, it can play a simultaneous zoomingeffect since different fields of views, hence different zooming, aretaking simultaneously.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to FIGS. 4 and 5. FIG. 4 is a schematic perspective viewillustrating the outer appearance of an optical apparatus according toan embodiment of the present invention. In FIG. 4, the boresight viewingdirection of each lens group, i.e., the corresponding optical axis, isplotted. FIG. 5 is a schematic cross-sectional view illustrating aportion of the optical apparatus of FIG. 4 and taken along the line L-L.As shown in this FIG. 5, the corresponding FOV is denoted. In thisembodiment, the optical apparatus 3 is an optical image capturingapparatus. The optical apparatus 3 comprises a first optical lens group31, a second optical lens group 32, a third optical lens group 33, afourth optical lens group 34, a fifth optical lens group 35, an opticalsensor 36, a filter 37, a light shielding plate 38 and a casing 39. Theoptical lens groups 31˜35, the optical sensor 36, the filter 37 and thelight shielding plate 38 are generally accommodated and fixed within thecasing 39. Once the casing is with common cam curve and following thecam curve, a zoom, i.e., not fixed, lens may be achieved. Nevertheless,the traditional zoom is not the topic to be addressed here. It is aspecial consideration of zooming flexibility here, however. The zoomingflexibility is embedded within more FOV available to lens groups(views). It should be noted that although it is the concept of field ofview to be illustrated in this patent application, the field of view canbe defined a specified area with a specified distance. Hence, theproposal of application here can be applied to the imaging of near-byobject where FOV has to be modified.

The first optical lens group 31 comprises a first lens 311, a fourthlens 312 and a seventh lens 313, which are sequentially arranged alongthe direction of a first optical axis 314.

The third optical lens group 33 comprises a third lens 331, asixth lens 332 and a ninth lens 333, which are sequentially arrangedalong the direction of a third optical axis 334. The fourth optical lensgroup 34 comprises plural lenses (not shown), which are sequentiallyarranged along the direction of a fourth optical axis 344. The fifthoptical lens group 35 comprises plural lenses (not shown), which aresequentially arranged along the direction of a fifth optical axis 354.The arrangement sequences of the lenses of the fourth optical lens group34 and fifth optical lens group 35 may be identical to or different fromthe arrangement sequences of the first optical lens group 31, the secondoptical lens group 32 or the third optical lens group 33.

Moreover, when light beams pass through any of the optical lens groups31˜35, the travelling directions of the light beams are changed. Afterthe light beams pass through any of the optical lens groups 31˜35, thelight beams are received by the optical sensor 36 and converted into animage signal by the optical sensor 36. The image signal is processed bya signal processor (not shown) or shown on a display device (not shown).

Moreover, each lens is made of a plastic material, a glass material or asilicon-based material. As shown in FIG. 5, each of the first opticallens group 31, the second optical lens group 32 and the third opticallens group 33 comprises plural lenses, which are in a stack arrangement.As seen from FIG. 5, the lenses of central portion indicated by 334 isdifferent from lenses which are indicated by 314 (and 324) which meansthe effective focal lengths may be different. On the other hand, it is aplanar image sensor to be used here and therefore the all images are onthe same plane, i.e., the sensor. It is noted that the number of lensesis not restricted. For example, in some embodiments, each of the opticallens groups 31˜35 only comprises a single lens.

Preferably but not exclusively, the first lens 311 of the first opticallens group 31, the second lens 321 of the second optical lens group 32,the third lens 331 of the third optical lens group 33, the correspondinglens of the fourth optical lens group 34 and the corresponding lens ofthe fifth optical lens group 35 are connected with each other. That is,these lenses are integrally formed on a single transparent structure.Similarly, the fourth lens 312 of the first optical lens group 31, thefifth lens 322 of the second optical lens group 32, the sixth lens 332of the third optical lens group 33, the corresponding lens of the fourthoptical lens group 34 and the corresponding lens of the fifth opticallens group 35 are connected with each other. That is, these lenses areintegrally formed.

That is,these lenses are integrally formed.

Since the corresponding lenses of the optical lens groups 31˜35 areintegrally formed with each other, the optical apparatus 3 can beassembled more easily. Moreover, since the optical apparatus 3 has theadvantage of miniaturization, the optical apparatus 3 can be applied toa handheld mobile device such as a mobile phone, a tablet computer orany other wearable device.

The light shielding plate 38 is located at the front sides of theoptical lens groups 31˜35. Moreover, the light shielding plate 38 hasplural perforations 381 corresponding to the optical lens groups 31˜35.That is, the optical lens groups 31˜35 are exposed outside through thecorresponding perforations 381. Consequently, the ambient light beamscan be introduced into the optical lens groups 31˜35. The lightshielding plate 38 is used for sheltering the surrounding stray lightaround the optical lens groups 31˜35. Consequently, the opticalresolution of the light beams to be sensed by the optical sensor 36 willbe enhanced.

The filter 37 is arranged between the optical lens groups 31˜35 and theoptical sensor 36. After the light beams pass through the optical lensgroups 31˜35, portions of the light beams are filtered and sieved by thefilter 37. Consequently, the light beams received by the optical sensor36 are useful light beams. For example, according to the practicalrequirements, the filter 37 is designed to block visible light beams,infrared light beams, near infrared light beams and/or far infraredlight beams.

In this embodiment, the third optical lens group 33 is a center opticallens group, and the first optical lens group 31, the second optical lensgroup 32, the fourth optical lens group 34 and the fifth optical lensgroup 35 are peripheral optical lens groups around the center opticallens group.

Since the optical lens groups 31˜35 may comprisedifferent numbers and/or different optical properties of lenses, theeffective focal lengths of any two optical lens groups are identical ordifferent. In an embodiment, f_(c) is an effective focal length of thecenter optical lens group (i.e., the effective focal length of the thirdoptical lens group 33), f_(e,j) is an effective focal length of the j-thperipheral optical lens group (i.e., f_(e,1) is the effective focallength of the first optical lens group 31, f_(e,2) is the effectivefocal length of the second optical lens group 32, f_(e,3) is theeffective focal length of the fourth optical lens group 34, and f_(e,4)is the effective focal length of the fifth optical lens group 35), andF/# is a f-number of the center optical lens group (i.e., the f-numberof the third optical lens group 33). Moreover, the optical apparatus 3satisfies the following mathematic formulae:

${0.6 < \frac{f_{c}}{f_{e,j}} < 1.2};$ and${\frac{f_{c}}{F/\#} < {2.5\mspace{11mu} ({mm})}};$

That is, the quotient of the effective focal length of the third opticallens group 33 divided by the effective focal length of the first opticallens group 31, the second optical lens group 32, the fourth optical lensgroup 34 or the fifth optical lens group 35 is in the range between 0.6and 1.2, and the quotient of the effective focal length of the thirdoptical lens group 33 divided by the f-number of the third optical lensgroup 33 is smaller than 2.5. Consequently, the performance ofconverting the received light beam into the image signal by the opticalsensor 36 will be enhanced.

Or, the optical apparatus 3 satisfies the following mathematic formulae:

${0.6 < \frac{f_{c}}{f_{e,j}} < 1.2};$ and${\frac{f_{c}}{F/\#} < {2.5\mspace{11mu} ({mm})}};$

That is, the quotient of the effective focal length of the third opticallens group 33 divided by the effective focal length of the first opticallens group 31, the second optical lens group 32, the fourth optical lensgroup 34 or the fifth optical lens group 35 is in the range between 0.6and 1.2, and the quotient of the effective focal length of the thirdoptical lens group 33 divided by the f-number of the third optical lensgroup 33 is smaller than 1.1. Consequently, the performance ofconverting the received light beam into the image signal by the opticalsensor 36 will be enhanced.

Or, the optical apparatus 3 satisfies the following mathematic formulae:

${0.2 < \frac{f_{c}}{f_{e,j}} < 2.0};$ and$\frac{f_{c}}{F/\#} < {1.1\mspace{14mu} ({mm})}$

That is, the quotient of the effective focal length of the third opticallens group 33 divided by the effective focal length of the first opticallens group 31, the second optical lens group 32, the fourth optical lensgroup 34 or the fifth optical lens group 35 is in the range between 0.2and 2.0, and the quotient of the effective focal length of the thirdoptical lens group 33 divided by the f-number of the third optical lensgroup 33 is smaller than 1.1. Consequently, the performance ofconverting the received light beam into the image signal by the opticalsensor 36 will be enhanced.

Moreover, these optical lens groups 31˜35 have respective (in otherwords, specific) fields of view (FOV) if an object is specified at afar-away distance, or these optical lens groups 31˜35 have a specifiedarea of image to be taken at a specified distance. Since the opticallens groups 31˜35 may comprise different numbers and/or differentoptical properties of lenses, the FOVs of any two optical lens groupsare identical or different. In an embodiment, FOV_(c) is a FOV of thecenter optical lens group (i.e., the FOV of the third optical lens group33), and FOV_(,j) is a FOV of the j-th peripheral optical lens group(i.e., FOV_(e,1) is the FOV of the first optical lens group 31,FOV_(e,2) is the FOV of the second optical lens group 32, FOV_(e,3) isthe FOV of the fourth optical lens group 34, and FOV_(e,4) is the FOV ofthe fifth optical lens group 35). Moreover, the optical apparatus 3satisfies the following mathematic formula:

$0.2 < \frac{{FOV}_{e,j}}{{FOV}_{c}} < 3$

That is, the quotient of the FOV of the first optical lens group 31, thesecond optical lens group 32, the fourth optical lens group 34 or thefifth optical lens group 35 divided by the FOV of the third optical lensgroup 33 is in the range between 0.2 and 3. Consequently, the imagingperformance of the optical apparatus 3 is enhanced. Preferably, when thecentral view is with typical FOV, e.g., 60-80 degrees. The associate FOVfor the other peripheral optical lens group may be larger than 180degrees which corresponding to a function of panoramic view. On theother hand, a minimum FOV with less 20 degrees or even 5 degrees isspecially designed for far-field viewing with telescope application.

Preferably but not exclusively, the inclined angle between the thirdoptical axis 334 of the third optical lens group 33 and each of thefirst optical axis 314 of the first optical lens group 31, the secondoptical axis 324 of the second optical lens group 32, the fourth opticalaxis 344 of the fourth optical lens group 34 and the fifth optical axis354 of the fifth optical lens group 35 is smaller than 20 degrees. Thatis, the inclined angle between the center optical lens group and anyperipheral optical lens group is smaller than 20 degrees. Consequently,the imaging performance of the optical apparatus 3 is enhanced.

In another embodiment, an inclined angle between a center optical axisof the center optical lens group and a peripheral optical axis of atleast one of the plural peripheral optical lens groups is more than 20degrees when the corresponding optical lens groups are embedding withreflective optical elements

Optionally, one of the plural optical lens groups 31˜35 is a visibleoptical lens group and another of the plural optical lens groups 31˜35is an invisible optical lens group. After a visible light beam passesthrough the visible optical lens group, a travelling direction of thevisible light beam is changed. After an invisible light beam passesthrough the invisible optical lens group, a travelling direction of theinvisible light beam is changed.

It is noted that the present invention is limited to the aboveembodiment. Those skilled in the art will readily observe that numerousmodifications and alterations may be made while retaining the teachingsof the invention. For example, in a variant example, the opticalapparatus is not equipped with the filter 37. In another variantexample, the optical apparatus is not equipped with the light shieldingplate 38. In the above embodiments, the light shielding plate 38 islocated at the front sides of the optical lens groups. In some otherembodiments, the light shielding plate 38 is located at another properposition of the optical apparatus. For example, the light shieldingplate 38 is arranged between two optical lens groups, or the lightshielding plate 38 is arranged between two lenses of a specified opticallens group.

In the above embodiment, the optical apparatus comprises a single filter37. In some other embodiments, the optical apparatus comprises pluralfilters corresponding to plural optical lens groups. Optionally,according to the special requirements, any two filters are designed toblock the same kind of light beams or block different kinds of lightbeams.

From the above descriptions, the present invention provides the opticalapparatus. The plural optical lens groups of the optical apparatus aredesigned according to different optical functions. For example, theoptical functions include a wide-angle imaging function, a non-wideangle imaging function, a long-distance imaging function and ashort-distance imaging function. It should be noted again that althoughit is the concept of field of view to be illustrated in this patentapplication, the field of view can be defined to be a correspondinglyspecified area with a specified distance. Hence, the proposal ofapplication here can be applied to the imaging of near-by object whereFOV has to be modified. The proposal of applications here also can beapplied to some lens groups are specified with FOV and some arespecified by area with distance. Moreover, the plural optical lensgroups are fixed in the same casing, and the same optical sensor isshared by the plural optical lens groups. Consequently, the opticalapparatus of the present invention has a single optical lens module, andis able to implement different optical functions simultaneously. Forexample, the optical apparatus can acquire plural images correspondingto different optical functions in each capturing process. Consequently,the overall volume of the optical apparatus is minimized, and thefabricating cost of the optical apparatus is reduced.
